CVE-2025-54740

Vulnerability

Description

The Print My Blog plugin for WordPress contains a stored cross-site scripting (XSS) vulnerability due to improper neutralization of user input during web page generation. Versions up to and including 3.27.9 fail to sanitize input that is later rendered in the admin interface or other blog pages, allowing malicious scripts to persist [1].

Exploitation

Details

An attacker with contributor-level privileges or higher can inject arbitrary JavaScript or HTML into the plugin's input fields. When a privileged user (such as an admin) views the affected page, the payload executes. This requires the target user to perform an action like clicking a link or visiting a crafted page, but no direct user interaction from site visitors is needed for storage; the script runs automatically when the page is rendered [1].

Impact

Successful exploitation enables the attacker to execute malicious actions in the context of the victim's session, such as redirecting visitors to phishing sites, injecting advertisements, or stealing sensitive data (e.g., cookies or tokens). This can be used in mass-exploit campaigns targeting thousands of WordPress sites [1].

Mitigation

The vendor has released version 3.27.10, which fixes the vulnerability. Users are strongly advised to update immediately. Those unable to update should consult their hosting provider for assistance. Plugin auto-updates can be enabled to apply future security patches automatically [1].
